Dr. Corcoran has been extensively involved in the development of inhaled medications for lung transplant recipients and cystic fibrosis patients and the development special techniques for improving inhaled drug delivery such as the use of low density gases and surfactants to improve drug distribution in the lungs. Dr. Corcoran had developed imaging techniques for quantifying pulmonary physiology including measurements of mucociliary clearance and liquid absorption in the airways. These techniques have been tested in a series of clinical studies involving adult and pediatric patients and will be used to screen new medications for treating lung diseases such as cystic fibrosis.
